Populazzi by Elise Allen and Saving Maddie by Varian Johnson both match the first cover but feature different necklaces. Populazzi is out at the beginning of August with Harcourt Children’s Books (a division of Houghton Mifflin Harcourt), while Saving Maddie is the oldest of the bunch: it came out in 2010 with Delacorte Books for Young Readers (a Random House imprint).

Seeing them all together, the skin colour of the first woman looks wrong!

I followed over from Susan McBride's fb link. I've seen and commented on the first two covers, but hadn't seen the others. I was actually surprised, wondering if publishing houses didn't search out more to avoid similar cover looks.
